GAS FURNACE.

Application filed September 22, 1926.

This invention relates to improvements in house heating gas furnaces of the type in which the burning gas is completely enclosed and passes through a radiator or drum and causes the air coming in contact with the radiator to be heated.

The principal object of my invention is to provide a gas furnace of this type with a radiator so constructed that the gas passing through the same, from the burner to the outlet, is retarded and directed in such passage so that a very large percentage of the heat of combustion is transferred to the walls of the radiator with practically equal intensity over the entire surface of said walls, thereby giving great heating etiiciency.

A further object of the invention is to con struct the radiator so that any moisture from the condensation of the gas will be positively drained from the radiator, thus eliminating the main cause of deterioration and corrosion of such radiators.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of ref erence indicate corresponding parts in the several views:

Fig. 1 is a sectional elevation of my improved funace construction.

Fig. 2 is a cross section on the line 2-2 of Fig. 1.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes the outer shell or casing of the furnace of suitable size and construction having an air intake opening 2 adjacent its lower end and suitable air outlet fines at the top.

Mounted centrally in the casing is a vertical gas chamber 4 closed both at top and bottom and having gas burners 5 of suitable character therein near the bottom. A lateral air passage 6 from said chamber at the bottom leads to a point outside the casing, thus providing air for the burners without the possibility of such air or the products of combustion coming in contact with the air inside the casing.

Surrounding the chamber 1 in spaced relation. thereto and extending from the top at Serial No. 136,954.

the chamber to a point short of the bottom thereof and above the air intake 2 is a continuous radiator B. This radiator consists of outer and inner side walls 7 and 8 with top and bottom walls 9 and 10 so as to form a complete enclosure. These walls are so arranged that substantially rectangular ver tical chambers 11 and 12 are formed at diainetrally opposed points, while between said chambers the walls are formed as deeply indented angular corrugations 13, symmetrically disposed relative to the central chamber 4. The corrugations of both walls are substantially parallel to each other and are considerably closer to each other than at the chambers 11 and 12, so as to form relatively restricted passages between said chambers. A horizontal passage 14 leads form the top of the chamber 4 on one side thereof to the chamber 11, while a discharge flue 15 leads from the bottom of said chamber 11 to the outside of the casing 1. The fine 15 at its junction with the chamber has a short vertical portion 16 depending from the bottom member 10 of the radiator, so that the fine is on a lower level than said bottom, sloping thence downwardly so as to drain properly.

Substantially midway between the top and bottom of the radiator, a horizontal battle plate 17 is mounted therein. This battle has a slight downward slant from the chamber 11 toward the chamber 12 and has an opening 18 therethrough only at said chamber 12. The bottom plate 10 of the radiator has a slope in the opposite direction to that of the battle plate or from the chamber 12 toward the chamber 11 and flue 15.

In operation when the burners 5 are lit and air is drawn thereto through the passage 6, the resultant products of combustion pass upwardly through a central chamber 4 from which they can only escape through the passage 14 into the chamber 11 of the radiator. To reach the discharge flue 15 the gases must then pass to the chamber 12 on the other side, thence downwardly through the baille opening 18 and again close the radiator to the chamber 11 and discharge flue. In passing from the chamber 11 to the chamber 12 and vice versa, the gases must pass through the restricted passages extending between said chambers and formed by the corrugated walls. The particular formation of these passages not only retards the passage of the gases but owing the zig-zag shape of passages the gases are thrown back and forth between the inner and outer walls. This cause. said walls to absorb a very great percentage of the heat from the gases and every portion of the surface area of said. walls therefore equal heat. Practically all available heat from the gases is therefore utilized. The shape of the corrugated zig-Zag passages also eliminates any pockets which cause the formation of eddys in the The discharge flue 15 being lower than the bottom of the radiator, said bottom gets the value of all l eat from the outgoing and is therefore at least as hot as any gases leaving the radiator.

The baffle plate and the bottom member of the radiator having a downward slope in the direction of travel of the gases. prevents moisture of condensation from collect mg "in the radiator and all such moist 1."

carried offxas formed.

The "relatively large vertical chambers at the ends of the zigzag passages allow the gases after leaving such passages to be con-- oentrated or collected in one or the other of'said chambers and tlun slid out again as said gases divide and pass through the zig-zag passages which branch oil from said vertical chamber.

From the foregoing description it will readily seen that l have produced such a device as substantially fulfills the objects of the invention'a set forth herein.

While this specification. forth in detail the present and preferred construction of the device, still in practice such deriations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

2. In a gas furnace, a radiator consisting of vertical and continuous outer and inner walls spaced apart and closed at top and bottom, chambers formed between said walls at the opposite sides thereof, zig-Zag passages between said chambers formed by corrugated said inner and outer walls in substantially para lel relationship to each other, and gas intake and outlet passages from the radiator at the top and b tternthereof respectively.
